10 years agodrm/nouveau: fix fbcon not being accelerated after suspend

drm/nouveau: fix fbcon not being accelerated after suspend

This does *not* (and is not intended to) fix the issue reported by
Christoph Rudorff on the nouveau mailinglist.

The patch proposed (which is similar to this one, but also reorders
whether we disable accel or call fb_set_suspend first), papers over
another problem entirely by avoiding touching the framebuffer.

10 years agosupport for platform devices
Alexandre Courbot [Mon, 17 Feb 2014 06:17:26 +0000 (15:17 +0900)]
support for platform devices

Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead
of PCI to which Nouveau is tightly dependent. This patch allows Nouveau
to handle platform devices by:

- abstracting PCI-dependent functions that were typically used for
  resource querying and page mapping,
- introducing a nv_device_is_pci() function that allows to make
  PCI-dependent code conditional,
- providing a nouveau_drm_platform_probe() function that takes a GPU
  platform device to be probed.

Core code as well as engine/subdev drivers are updated wherever possible
to make use of these functions. Some older drivers are too dependent on
PCI to be properly updated, but all newer code on which future chips may
depend should at least be runnable with platform devices.

Highlights
----------

Re-factoring works over the exynos drm framework.
  - drm_crtc, drm_encoder/drm_connector are implemented by sub drivers
    directly.
  - Removing pm interfaces from each sub driver, and implementing them
    at top level of exynos drm.
Add DisplayPort Transmitter driver.
  - Just moving existing driver from drivers/vides/exynos into
    drivers/gpu/drm/exynos.
Add new LVDS bridge driver, PTN3460.
  - Placed in drivers/gpu/drm/bridge, and this device is used to transfer
    image signal from DP(DisplayPort) to LVDS Panel.
    So this driver will be used with DP driver moved into exynos drm.
Add parallel panel support
  - With the re-factoring patch series, existing parallel panel support was
    broken by moving exynos_drm_display ops into each real connector driver,
    DP. So this patch series adds a new parallel panel module,
    exynos_drm_dpi, for supporting parallel panel, and also adds relevant
    bindings.
Some fixups and cleanups.

drm/exynos: Use drm_mode_copy to copy modes

This patch changes the manual copying of mode to adjusted_mode in
mode_fixup to use drm_mode_copy instead of handling things manually.

10 years agodrm/exynos: Remove exynos_drm_hdmi shim

drm/exynos: Remove exynos_drm_hdmi shim

This patch trims exynos_drm_hdmi out of the driver. The reason it
existed in the first place was to make up for the mixture of
display/overlay/manager ops being spread across hdmi and mixer. With
that code now rationalized, mixer and hdmi map directly to
exynos_drm_crtc and exynos_drm_encoder, respectively. Since there is a
1:1 mapping, we no longer need this layer.

10 years agodrm/exynos: hdmi: remove the i2c drivers and use

drm/exynos: hdmi: remove the i2c drivers and use

The i2c client was previously being passed into the hdmi driver via a
dedicated i2c driver, and then a global variable. This patch removes all
of that and just uses the device tree to get the i2c_client. This patch
also properly references the client so we don't lose it before we're
done with it.
